There are differing opinions on this. If you are in the business of breeding horses they may breed a younger mare. I think the youngest age should not be before 6 or 7 years old. This gives enough time to let the horse mature and get her broke to ride before she becomes a mother.
Answer- wait until she is at least 3 years old so that she has the majority of her growth.
Male and female horses both can live to the same age. A fair life expectancy is 25 years old, although many will live in perfect condition into their 30's. Some breeds will deteriorate longer than others. For example, it is known that a Suffolk Punch can live to 40 years old, whilst a successfully raced thoroughbred may be lucky to reach 30.
Well-grown fillies (young female horses) can be bred when they are two years old so they will first foal when they are three years of age
Mares have a estrus cycle, not a menstrual cycle like a human female and therefore do not have a period.
18 months
The best way to recognize when your female dog has her first heat cycle is to spot the drops of blood that will come from her rear. Her female parts will also appear swollen.
The first heat cycle for a female dog would be between 6-24 months. If she doesn't have her first cycle by then, you take a trip to the vet. And it doesn't necessarily matter what kind of dog it is to have a certain heat cycle. Hope this helps!
Horses are pregnant for 11 months. A "normal" horse gets her first heat cycle at around 3 years of age.
There is no reason to give a female dog medications for a first heat. Having a heat cycle is a normal thing for a female dog. If you are not going to breed her, then have her spayed as soon as she is out of heat. She will live a longer and healthier life. Cut down her risks of mammary tumors, uterine infections, perianal tumors, etc.
When a female cat is in heat it is called Estrus --This is the name of the cycle. The name of the cat itself is a queen. == ==
They can be bred when they have their first heat cycle which can be as early as four months but is more typically around six months. It is generally not recommended to breed a dog on it's first heat.
When the female goes into heat, can be any time of the year
3 weeks

Female dogs of all breeds have menses (called the "heat cycle", or estrus) twice a year on average starting at around 7-10 months of age. A female dog will gain the most in health benefits if they are spayed before they have their first heat cycle.
A donkey's heat cycle can vary since no two donkeys are the same. However, the average heat cycle tends to be anywhere between 23 and 30 days.
I will assume you are talking about the dog's heat cycle. A female dog does not have a menopause, as people do. Their cycles continue their entire life, though in it's elder years the cycle can become less predictable as to when it occurs. A female dog no matter it's age can become pregnant, but that doesn't mean it's healthy for an older dog! This is why female dogs need to be spayed, preferably before the onset of their first heat cycle.
